although there must be adjustments and adaptations but I feel that he is very easy to socialize there so this is not too much of a problem.
But until now the deal is still not there and this is what makes it difficult for PSG.
Maybe if he managed real Madrid since those days, they wouldn't get another but ancelotti got it? Who knows, is there a guarantee that it would happen? Or if he goes to PSG today, maybe they won't even win the league let alone UCL, is there a proof? We just need to wait and see.
I don’t think that Zidane will guarantee instant champions league at PSG, because he’ll require at least two full seasons to build the team in his image, but PSG owner’s are impatient and he’ll probably be sacked before that. Lastly it’ll be interesting to see him perform at PSG as it’s a weaker league, and Champions League is difficult hence we should not expect much from Zidane especially when it comes to champions league.
